Hi! I have removed the 215 (?) from my 48 chevy 2 ton because engine was stuck. Now I am down to the bare block with one piston stuck mid stroke. I have used generous amounts of penetrating oil on the piston and rotated upside down and lubricated bottom of cylinder as well for a week or so.
Can anyone suggest any method of coaxing that last piston out, preferably without damaging the piston, connecting rod or cylinder too badly?
